Abstract : Opportunistic networks are generally characterized by a low performance due to user mobility and non end-toend communications, which makes it challenging to use them in scenarios involving the transmission of large data, such as video transmission. This article presents simulated experiments of transmitting videos in opportunistic networks, with the objective of enhancing user video viewing experience. We consider this concept as a trade-off between playout delay and the delivered quality level. To obtain the best trade-off, we propose using Scalable Video Coding, SVC, which divides a video into multiple unequally important layers, providing different levels of quality. This property is exploited to transmit video layers with unequal degrees of redundancy proportionally to their degree of importance. Experiments were performed on different video sequences to measure the two objective criteria. Results show that this approach enables the video to become more quickly playable at the destination with a low starting quality but progressively being enhanced, providing a better viewing-experience.
